Video Watermark Detector
Audit video for inspectable provenance: C2PA/JUMBF, XMP, generator signatures, and container metadata. For MP4/MKV/AVI we show a safe metadata-stripping recipe without re-encoding.

Fatos principais
Upload an MP4, MOV, MKV, WebM or AVI video up to 80 MB and the tool checks the container for C2PA (Content Credentials), XMP and signatures of Sora, Runway, Pika and Kling. Free, no sign-up. It does not decode a mark embedded in the frames or the audio, and it does not rewrite the video.
- Preço
- Grátis
- Cadastro
- Não é necessário
- Processamento
- The file is uploaded to our server and examined by a Python module; the copy sits in a temporary folder and is deleted by a timer
- Entrada
- One video file in MP4, MOV, M4V, MKV, WebM or AVI format, up to 80 MB
- Limites
- 6 checks per minute per IP; no sign-up; files over 80 MB are rejected; the container and metadata are analysed, not the frames or the sound
- Resultado
- A report with findings and a risk level: C2PA/JUMBF records, XMP fields, generator signatures (Sora, Runway, Pika, Kling and others) in container metadata, and a recommendation with an ffmpeg command to clean the metadata

Video Watermark Detector — C2PA, Metadata and AI Signatures
Check a video file for C2PA/JUMBF provenance, XMP, and AI video generator names stored in container metadata, such as Sora, Runway, Pika, Kling, and more. The tool shows risk, findings, and an ffmpeg command to strip container metadata without re-encoding. It does not analyse visible logos or SynthID inside frames.
Como usar
- Upload a video within the page limit.
- Review detected C2PA/XMP/generator signals and the risk score.
- If metadata cleaning is needed, apply the shown ffmpeg recipe to your source file.
Casos de uso
- Audit video before publishing to social channels, ad accounts, and landing pages.
- Inventory AI provenance in UGC and contractor creatives.
Limitações
- Does not remove visible logos, subtitles, or watermarks rendered into frames.
- For large videos, use local ffmpeg cleanup based on the report recipe.
- MKV and WebM are scanned only in the first 128 KB; MP4/MOV are scanned through their metadata boxes.
Exemplo de entrada / resultado
promo-video.mp4 with a C2PA manifest in the container
Risk 100%; found C2PA manifest (Content Credentials); command: ffmpeg -i in.mp4 -map_metadata -1 -c copy out.mp4.

Role a tabela para os lados
Onde somos mais fracos: we do not read or verify the C2PA manifest signature in depth, cannot decode marks inside frames and do not edit the file itself; the limit is 80 MB.
Quando escolher o PromoPilot: When you want to know quickly whether a video still carries Content Credentials, XMP or traces of an AI generator in its metadata, without installing command-line utilities. For marks hidden inside the frames, use the model developers' own tools.
